Hey, I was just curious how many people have gotten newer transmissions and switched thier B13 to hydrolic clutch? I have done a manual to automatic swap on a honda accord before and it was not very fun. Does the pedal assembley froma b14 bolt into a b13? Is a b14 tranny even hydrolic? SOrry , pretty newbish in the se-r scene

How can you be here from Oct 2002, with 324 posts, and be newbish? :confused:

Oh well, if you say so...Mr. Newb.

Read this thread:

http://www.sr20forum.com/showthread.php?t=149841

It will teach you how to effectively search. Seriously good tips in there on getting good results instead of frustrated. In addition, post #6 will direct you to the Tech Library.

The Tech Library (button at top of every page) is filled with wondrous, detailed, write-ups on fixes and upgrades.

It has two (2) threads that you should read:

http://www.sr20forum.com/showthread.php?t=101560

http://www.sr20forum.com/showthread.php?t=97257

Read both of those threads and you will know your answers. In fact, you should scan all the articles in the Tech Library until you are familiar with what articles are in there.

Good luck.

Thanks man. I am newbish because I joined as a 240sx /datsun 510 guy in 2002. I really didn't start being active untill abour a year ago when I still had my 510. I just picked up a Sentra, so I am reading and learning more on fwd setups.

You had me totally confused. OK. :)

Well, the threads in the Tech Library will clue you in... You would want to go B15/P11 tranny, and convert it from hydraulic to cable activation. Not the other way around.

The one thread tells you how to do it.

The other thread tells you why the B15/P11 tranny is so much stronger/better.

Good luck.

Thanks man. I saw that post and how they converted from hydrolic to cable. I was curious about the cable to hydrolic conversion because I might get my hands on a b14 transmission, are those hydrolic? WHat are the pros n cons of hydrolic vs cable? I wouldn't mind the ease of having hydrolic force. For some people that have never took apart a tranny, a hydrolic conversion might b easier than taking the tranny apart and having little springs and little pieces falling out on you.

B13 and B14 trannies are cable actuated. One of the slickest shifting, light effort, trannies you will ever drive. No need whatsoever for hydraulics to help.

I don't know the pro's and con's of cable and hydraulic. I'm mechanically clueless. I just read a lot.

Don't try to re-invent the wheel my friend. The mechanical geniuses, yes geniuses, on this forum have already worked on our tranny issues forever. From motor mounts, to tranny fluid, to every swap concievable, it has all been considered.

NO need to convert anything to hydraulic. The only way that scenario needs to go is find a P11/B15 tranny, convert it from hydraulic to cable actuation, and install it in your B13/B14. :)

yeah, i was just curious. For someone like me or a lotta people on this forum, they can do that themselves, but if they were not as mechnically inclined, maybe a pedal and lines would b easier and cheaper. Yeah, u are right though, "why try to reinvent the wheel" Thanks guys

Converting to hydrolic would be a PITA as Shawn stated, the B14 is cable also so it will bolt right into the B13 (basically the same tranny).

Hydro conversion would require the clutch MC, clutch slave cylinder, hard lines, some soft lines, probably a diff't clutch pedal - and most would probably not bolt into a B13. Not worth it, stick to the cable since it is just a pedal and a line.

Also, the B14 tranny isn't really and upgrade on a B13. Did you mean B15 for your Classic?

Josh is right. The B14 tranny is a minor upgrade, some 5th gear internal upgrade or some such thing. B14 trannies can still go out even though Nissan did a "band-aid" fix on it over the B13. Probably less likely to break (maybe), but not a thorough fix by any means.

The B15/P11's (read the threads, you have to get the correct "newer" B15 tranny) are completely redesigned, the case, some guts, etc..... Folks are holding big horsepower with no issues.

Josh, didn't we talk about this before? :tongue:

I hear cable is better anyway, hydro tends to heat up and clutch activation tends to fade under racing conditions just like breaks because the fluids heat up and thin out.

Thanks for the help guys, i really appresciate it. Honestly though, the search is good, but sometimes you need some info not discussed in previous posts. Besides, if that were the case, I believe almost every subject has been covered in these forums. SO what would b the piont in posting, we mightas well read old posts all day. Most of our cars are from the 90's , so I am pretty sure all the sujects posted right now couild b a repeat. Please bare with us noobs. I been using the search , but did not find a specific "cable to hydro " conversion. Not that I was going to do it, but seeing if anyone has. Thanks for the input
